It is the third acquisition of the year for Spotify, which snapped up Ireland's Soundwave, a music discovery application, and Cord Project, a US-based voice messaging service for phones, tablets and smartwatches, in January.

Financial details of the CrowdAlbum acquisition were not disclosed.

Spotify, which claims more than 30 million paying subscribers in 59 countries, raised a billion dollars in financing through convertible bonds in March, according to The Wall Street Journal.
